Be it known that I, DAVID T. SHARrLEs,

"a citizen of the United States, residingat West Chester, inI the county ,of Che-storend State of Pennsylvania, have invented an iin proved -Milking' Apparatus, 'of whichv "the "i tqllowing is a specification.

to .provide improved means for effecting a `desired pulsating action, vthe improvements comprlsing'a valve niecha'nlsm operated by a pendulum foreli'ecting the pulsations. s

In the-apparatus, in its preferred form, a. suction duct, the atmosphere and a pressure `duct are connected successively. with a cornpartment of a teat .cup surrounding the i-exible wall `ot' an interior. compartment i with which the suctionduct is lconnected through a milk receiver, the successive connections being effected-by the valve mecha` mism oscillated by the pendulum.

The mechanism has the, advantageot provinding the desired pulsatory action, variable in its time with variations in thedi'stance ofthe centery of 4gravity of the pendulum.

' from the center of oscillation.

In thel apparatus, a pressure pipe 1 and a lvacuum pipe 2 have connected therewith'a valve bodyprovided with the seats 3a land v3b, for engaging the pipes, and thethrea'ded .socket 3.i which is engaged the threaded end 4 of a hanger 4, the partsbeing clamped -together by a `clip 5 sleeved on the hanger in contact with .the pipes'and a nut Giscrewed down onr'the'threaded end' 4a against the "nectingits port withthe duct-1, the vpassagef connecting its -port'tnth the duct 2,

My invention relates 1.o milking apparatus.; ping thierendof t .of the pneumatic type", andv it is designed which the sleev'e is journaled and with freferi y ence to which it isadapted to be Withdrawn and inserted. v

In the form of the. invention illustrated in Figs. 1 tov'6 inclusive, the valve 7 is fixed to acasing 8 on the cover9 of the receptacle 10. A passage 7, in the valve, connects the #port 7d of the sleeve 7 with the chamber of the casing 8, which is connected through the port 9a in the cover 9 withfthe interior of the receptacle 1 0, the portv9 beingcontrolledby a puppet valve 8 movable in the guiding the receptacle 10.- To. regulate theoperation, the 'sleeve is adjustable upon the part 7 by` means of 'a tiange-f having a` rack?? and a screw ll-fjournaled in the bearing 12 .on the casing 8, the'screw having the thread 11a Whichengages the rack.

i The casing'S hasits chamber connected b v .the -fiexible tube 13 with the exterior chamber 14*v of a teat cup 14, which has its interior chamber 14b connected by the. flexible tube 15 'with a valve casing 16 communicating withthe interior of the pail 10,

Athe casing IGhaving a valve 16a therein for controlling the communication between the pail and the inner chamber of the teat cup..

A duct 17.` controlled bythe valve 17,

connects the interior-ofthe casing 8 with a motor cylinder. 1`8`onthe cover 9. A. piston 19 acts in the c vlinder andis adapted to make contact with the lug '2O fixed to the bodyfl.

In operation. the'pail 1 0 elevated and. the valve 7 is slipped 'into the bearing 3h; Then'the screw' 11 is revolvedandthe valve sleeve 7 is turned on itsyarbor to bring' its :port 7"1 into registration vwith the 3 with the pail in the vertical position. The. snction duct 2 now communicates'through the passages 3f and 7 with lthe casing ofthe chamber .8 and 'thence withlthe teat cup -`barrel 8b in the casing 8'. rI `he port 7d is 'brought into registration' with .the ports 3e, '31 and 13g, alternately, by the oscillation of compartment 114,-'11 through the duct 13, and

' with the teat cup compartment 14h through the port 9a, pail 10, open valve casing 16 and duct 15. The cup is now applied to the..

teat and the screw 1'1 isv adjusted to bring the port 7d tothe central position, in registration withthe port 3i, .upon which atmospheric pressure is admitted to the outer chamber'of the'teat cupiwhile the vacuum is maintained inthe inner chamber, lthe valve 8 'closing 'the' port 9a on the admission oflair of theteat cup. `Then the pail returns to the vertical position, bringing the ports 3i and 7d into registration, the vacuum is maintained in. the inner chamber of the teat cupxand 'atmospheric pressure is admitted tothe outer 'chamber thereof as previously describedf W hen. the movement of the" pail eects the registration of the port'sl'?)g and 7 d, suction is communicated from the duct 2 to the outer compartment of the teatcup, asI previously described, the desired vacuum 'in the inner compartmentof the teat cup being maintained yby Athe lifting of the valvea and suction through the'uncovered port 9.a.' The pendulation of the receptacle is maintained by the motor having the cylinder 18 Yand `piston 19 connected with the casing Siby thel duct 17. .VViththe valve 17a' set to vopen this duct to I`tliedesired degree and the ports 3e and 7d vin registration, compressed air enters the `cylinder 18, lifts the piston'19l (which makes contant with the lug 20) and swings the pail away from the lug, the return being eifected by gravity.

^ In "th, form of the invention',illustrated in Figs. and 8, the valve has its passage 'Tlicon` 1ieeted by a flexible tube 21 with the ea'singfS on' `the cover 9y ofthe pail 10, and the yalve'fis ioscillated by a pendulum 22 fixed thereto and provided with an adjustv `ah'le `'weight 23 by which the periodicity of V the pulsator can be varied. An arm 24 on the pendulum carries the cylinder 18- containing-the piston 19` adapted to make con- 'tacit4 `with `the stationary .lug 20, the cylinder being connected by the passage 17 with the The operation issimilar to that previously described, thescrew 11 being first revolved andacting through the flange f to adjpustthe sleeve 7 a so that the suction duct 2 shall be connected through the tube 21 with the .casing'S when the pendulum 22v is inthe 65,

vertical positionJ Suction is' thus applied to. the outer chamber of the teat'cup 14' through the tube 13 and to the inner chamber of the teat cup lthrough the port 9a (controlled by the valve 8a), pail 10, valvecasing 16\ (controlled-by the valve 16a) and tube 15. The cup is now placed on the teat, the screw v11 is turned to eifect communica tion between the atmosphere and the outer chamber-of the teat cup', the pendulum is started and the outer teat cup chamber. is

connected" sequentially with the pressure pipe 1, the atmosphere and the suction pipe 2, the movement being maintained by vthe motor. y y Y y VHaving described my invention, .l claim:
